Embodiment Construction

[0022] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0023] Specific embodiment one of the elastic support unit for the wall bushing assembly of the present invention, as Figure 2 to Figure 4 As shown, the wall bushing assembly includes an intermediate cylinder 1 and insulating sleeves 2 located at both ends of the intermediate cylinder 1 in the axial direction. The intermediate cylinder 1 and the insulating sleeve 2 together form a sleeve, and there is an insulating medium inside the sleeve. The housing chamber is provided with a hollow conductive rod 3 in the housing chamber, and a connecting flange 4 is sealed and fixed at the openings at both ends of the casing. The connecting flange 4 is provided with a conductive rod perforation, and one end of the conductive rod 3 is The conductive rod on the connecting flange 4 is pierced through the hole, and the pierced part forms the piercing section of the con...

Abstract

The invention relates to an elastic support unit for a wall bushing assembly to solve the problem that a conducting rod is easily damaged due to overlarge pretension force of an elastic support part in the prior art. The elastic support unit for the wall bushing assembly comprises the elastic support part which is used for being elastically supported between a connecting flange fixedly connected with the end part of a wall bushing and a stop structure fixedly connected with the end part of the conducting rod; a first flange structure which is used for being detachably connected with the connecting flange is fixedly arranged at one end of the elastic support part, and a second flange structure which is used for being detachably connected with the stop structure is fixedly arranged at the other end of the elastic support part; an adjusting part for adjusting the pretension force on the stop structure is also arranged between the first flange structure and the second flange structure; andthe acting force applied to a stop plate through the adjusting part in use is opposite to that applied to the stop plate through the elastic support part in direction.

Description

technical field [0001] The invention relates to an elastic support unit for a wall-piercing bushing assembly. Background technique [0002] UHV DC transmission is the best technical solution for large-scale long-distance transmission of new energy and other power, and is an important force to promote the development of low-carbon strategic emerging industries. In the next few years, the market demand for UHV DC wall bushings will increase significantly promote. Before 2020, my country is expected to build 23 UHV DC projects, and the market prospect is very broad. UHV DC SF 6 The gas wall bushing has the advantages of relatively simple structure and relatively light weight, and will be the mainstream direction of UHV DC wall bushing development in the future. UHV SF 6 The length of the central conductive rod for gas wall bushings is generally about 25 meters. If there is no support in the middle, the deformation is serious. Under UHV, the field strength distribution is di...
